The brain is an electric organ, and its 86 billion neurons communicate via pulses of electricity. When a voltage change causes one neuron to “fire,” it releases chemicals that trigger voltage. Jul 01, · Recording of spontaneous synaptic activity. All recordings were performed at room temperature (20–22°C). From five to 10 prisms of the electric organ were cut with a scalpel blade and 1–5 mm sections were incubated overnight in Torpedo saline solution containing galantamine, to ensure complete diffusion throughout the tissue. Fragments were fixed in a plexiglass chamber with a sylgard Cited by:

The electric eel has three pairs of abdominal organs that produce electricity: the main organ, the Hunter's organ, and the Sach's organ. These organs make up four fifths of its body, and give the electric eel the ability to generate two types of electric organ discharges: low voltage and high poldasulteng.com: Actinopterygii.
An organ system is a group of organs that together perform a function for the body. The digestive system, for example, consists of organs such as the mouth, the stomach, and the intestine (Fig. ). These organs work together to break down food and provide nutrients to the body. You searched for: toy organ!

May 31, · The procedure to obtain the electric organs is described here (also see Fig. S1). To explant a pair of electric organs, the electric ray was cooled for about 10 min on ice to anesthetize it. Then, the skin on the electric organs was detached using scissors from the dorsal side and a pair of tweezers was used to pull the skin poldasulteng.com by: 3.
May 04, · Background. During development, the branchial mesoderm of Torpedo californica transdifferentiates into an electric organ capable of generating high voltage discharges to stun poldasulteng.com organ contains a high density of cholinergic synapses and has served as a biochemical model for the membrane specialization of myofibers, the neuromuscular junction (NMJ).Cited by: Biosynthesis of Acetylcholinesterase in Rat Brain and Torpedo Electric Organ is Directed by Scarce mRNA Species HERMONA SOREQ, RUTI PARVARI and ISRAEL SILMAN Department of Neurobiology, The Weizmann Institute of Science, Rehovol (Israel) INTRODUCTION The principal role of acetylcholinesterase (AChE) is believed to be termination of impulse transmission by hydrolysis of the Cited by: 4.
In the present work, we have investigated the effect of antipsychotic drugs on cholinergic trans- mission and for this we have used the electric organ of Torpedo.
The choice of preparation may seem surprising: what is the reason for studying on an electric elasmobranch fish a series of drugs known for their action on the human brain?Cited by: 8.
The diadenosine polyphosphate hydrolase present in presynaptic plasma membranes from the Torpedo electric organ has been characterized using fluorogenic substrates of the form di-(1, N6.
Certain fish possess an electric organ that, on brain command, generates a three-dimensional electric dipole field around their bodies. Compared to incidental stray fields as measured close to any organism , an electric organ discharge (EOD) is characterized by a stronger amplitude, higher temporal and spatial stability, and a species-specific orientation that is adapted to its function.
The uptake of acetate and its incorporation into acetylcholine were measured under various conditions in nerve terminals isolated from the electric organ in order to characterize acetate uptake and to study the relationship between acetate uptake and acetylcholine synthesis in a pure cholinergic poldasulteng.com by: The weight of the brain of a dog, gorilla, and man, having approximately the same weight of body, has been found to be, and grams respectively.
The actual mass of the human brain is exceeded among animals only by that of the gigantic elephants and whales, the size of whose body is many times that of man. The Growth of Chalcedony (Nanocrystalline Silica) in Electric Organs from Living Marine Fish an Ar ion laser with emission bands in nm (cyan), nm (yellow) and nm (green).
The electric organ of skates is a paired structure within the tail consisting of two longitudinal columns of electrocytes contained within the lateral musculature on each side of the vertebral column.
Chol-1 antigen has been found to be specific for cholinergic neurons in the electric organ of Torpedo Marmorata and guinea-pig brain (1). The antiserum raised against synaptosomes from electric organ has been shown in mammalian brain to bind to a ganglioside antigen (Chol-1) localized on specifically cholinergic terminals (1,2,3) as shown by Author: Marie-Odile Jauberteau, P.
Richardson, M. Harpin, N. Baumann. Torpedo AChR is routinely purified from g of frozen Torpedo electric organs by affinity chromatography on cobra toxin-Sepharose, according to Gotti et al.
(30), with some minor modifications. The specific activity of the purified receptor is between and pmol of. Torpedo Electric Organ at biology web directory. Lophophore Information from Wikipedia on the characteristic feeding organ possessed by the three major phyla Brachiopoda Bryozoa and Phoronida.
Organ-pipe Mud-dauber: Trypoxylon politum Photographs and. The electric organs of certain electric rays are very good sources of AChR (10– µg/g), which can be extracted in detergent, usually 1% Triton X, from membrane preparations and purified by affinity chromatography using Sepharose columns to which one of the cobra (Naja naja) α-neurotoxins has been attached (Vincent, ; Lindstrom, ).
The Shocking History of Electric Fishes: From Ancient Epochs to the Birth of Modern Neurophysiology Astroscopus sp.) use their electric organs to produce powerful represented herself in.
Jun 15, · Soluble and membrane-bound low-Km 5'-nucleotidase was isolated from high-speed supernatants and membrane fractions derived from the electric organ of the electric ray (Torpedo marmorata) or from bovine brain cerebral cortex.
Purification of both enzymes included chromatography on concanavalin A-Sepharose and poldasulteng.com by: The central circuitry commanding the electric organ discharge (EOD) is well-known, and thus electrocommunication displays can be easily linked to the structures responsible for their modulation.

Aug 15, · Both enkephalin-hydrolysing activities in Torpedo electric organ are inhibited by 1,phenanthroline, like their mammalian counterparts.
The peptidases may function in the hydrolysis of endogenous peptides or in neurotransmitter exocytosis in the electric poldasulteng.com by: Bioelectricity, electric potentials and currents produced by or occurring within living organisms.
Bioelectric potentials are generated by a variety of biological processes and generally range in strength from one to a few hundred millivolts. In the electric eel, however, currents of one ampere at.This article contains a list of organs of the human body.
It is widely believed that there are organs; however, there is no universally standard definition of what constitutes an organ, and some tissue groups' status as one is debated.
Since there is no single standard definition of what an organ is, the number of organs varies depending on how one defines an organ.
